    This worked for me as well! So much easier than the other fixes. Mine just greyed out for no reason.

    I did not have to reset permissions. Both my user and group were "_coreaudiod" for that directory and the plist file it contained. Just ran the last two commands, clear cache, and restart daemon to fix the problem. Resetting PRAM doesn't sound like good advice. Thanks.

    This is the best, and easiest answer.  Should be a sticky.

    I Have the same problem after using headphone jack. After trying all the suggestions rebooting, Pram, disk repair etc all to no avail I realised it is mechanical problem with the jack. Fixed by moving headphone plug around in the jack until it sorted out . There must be a switch or something that gets stuck, I think.

    I went to Apple Button > System Pref  > Sound > Output

    Then I changed the output to the built-in speakers

    Then I plugged in headphones

    Changed output to headphones

    That fixed the problem for me. Hope that helps!

    Good call.

    As a slight variation on your recommendation ...

    I have the "Pro Tools First" application installed.

    In System Preferences > Sound > Output, "Pro Tools Aggregate I/O" was selected (though I have not used the Pro Tools First application in a quite a while, but I have used Logic Pro with my MOTU 8 Pre as sound output recently which is what I believe caused the system setting change).

    Choosing "Headphone Port" (my headphones were plugged into the audio jack) un-greyed out the Sound icon.

    Thanks, It worked for me too.

     

    I have attached the headphone and typed sudo killall coreaudiod on terminal couple of time and tried removing head phone couple of time. Thanks
